To all whom t may concern Be it kn own that l, CHARLES W. Kami-inn, acitizen of the United States, residing at Zillah, in the county ofYakima and State of lVashington, have invented certainznew` Anotherobject of the invention is to proi vide improved operating means for theclamp so that the clamp may be held in a lowered position while the lidis being nailed to the box and `to also provide improved means forguiding the vertical bars which carry the adjustably-mountedlid-engaging claws.`

This invention is illustrated in the accompanying drawings whereinFigure 1 is a side elevation of the improved press; Fig. 2 is a`vertical sectional view taken alongthe line 2-2 of Fig. l; Fig. 3 is anenlarged view of the upper-end portion of one of the vertical bars withthe lid-engaging claw shown in place; Fig. 4l is a fragmentary viewshowing the treadle in section and the rack in elevation.

This press is provided with a supporting table which is provided withthe corner standards 11 upon which the top 12 rests.

`'lhe forward standards 11 are connected by the cross bars 13 and 111and the rear standards are connected by the cross bars 15 and 16 andconnected with the forward standards by the angle bars 17 and side bars18. The various parts which form the table are secured together bysuitable bolts shown, and it 1will therefore be seen that the table willbe very strong in construction and not liable to easily come to piecesor wear out. Angle bars 19 are carried by the table top 12, but are notsecurely held to the top since it is desired that these angle bars maybe moved to accommodate themselves to the length of the box 20 whichthey support.

The treadle 21 has its rear end pivotally connected with the cross bar16 by means of i the hinge 22 and has its forwardend portionSpecification of Letters Patent.

passed the lower end of a bar24 which car- :ries a rack 25. A latch 2Gis carried by the treadle and engages the teeth of the rack 25 `toreleasably hold the treadle in a lowered position.` A. spring 27 has oneend connected with the treadle by means of the eye `bolt 28 and has itsupper end connected with `the'` table top by means ofthe eye bolt 2S).`This spring is provided to yieldably hold the treadle in the raisedposition shown in dotted lines in Fig.` 2. The rods 30 which areslidably mounted in slots formed in the table top have `their lower-endportions passed through the collars 3l and pivotally connected with thepivot pin32 which is` rotatably `connected with the treadleby` means ofthe bar 33. The collars 31 are adj ustably connected with the rods 30 bymeans of the setscrews 34 and are provided with eXtensions 35 so thatthe collars may be pivotally connected with the links 36. These links 3Ghave their outer-end portions pivoti ally connected with the pivotbrackets 87 which are secured to the angle bars 17 as shown in Fig. 1.

The claws 38 are adj ustably mounted upon t the upper-end portions ofthe rods 30 and are releasably held in place by the set screws 39. Eachof these claws comprises a sleeve 40 which carries the set screw 39 andforms a connecting means for the two arms 41 which extend in divergingrelation from the sleeve, as shown in Fig. 3 and have their upper endsbent to extend beyond the ends of the box lid, as shown in Fig. 1. Theupper ends of the arms are provided with en-` largedend portions 42which provide means for firmly gripping the box lid and prevent anydanger of the box lid being broken away when the treadle is moveddownwardly.

The operationof this machine is as follows: The box 20 is put upon thesupports 19 and the cover 423 is then put in place. The rods 30 are thenmoved to the proper position so that the claws 38 may engage the boxcover and the claws 3S adjusted to the proper position and the setscrews tightened. The treadle can `then be moved downwardly and thiswill cause the rods 30 to swing toward the center of the table until theclaws engage the box cover and Patented Oct. 27, 19ML.l

provided with a slot 23through whichis i then move downwardly `to theposition i ile the lowered position so that the operator can remove hisfoot from the `treadle while securing the cover with suitable nails. Thetreadle can then be moved to disengage the rack and the spring 527 Willthen return the treadle and rods to the normal Position. It is, ofvcourse, obvious that the claws lWill have to be adjusted upon the rods30 according to the size of the `boX and that the collars `3l areadjusted according to the amount it is desired to have `the rods 30swing outwardly When the treadle is in the raised position.

lli/That is claimed is:

2." A press lof the `character described comprising a support, a treadlecarried by said support, a pivot pin rotatably connected to saidtreadle, rods pivotally connected Wit said pin and extending above saidsupport,` article engaging means carried by said rods, guides adjustablyconnected with said rods,

and links pivotally connected With said guides and with said support.

. 3. A press of the character described comprising a support, a treadlecarried by said support and provided With a slot, a rack bar carried bysaid support and extending through said slot, a latch plate carried bysaid treadle and extending partially across said slot for engaging saidrack bar, means for yieldably holding said treadle in a1 normalposition, article-engaging means connected with said treadle, `andguiding means carried by said support andl adjustably con-V nected withsaid artcle-engagingmcans.

4. A press of the character describedv comprising a supporting frame,rods extending vertically throughy said frame, article-engaging meanscarried by said rods, collars slidably mounted upon said rods, means forreleasabl holdinov said collars in an adjusted position, links pivotallyconnectedr `amies of thispatent may be obtained for ve cents each, byaddressing the Commissioner of Patents,
